interior, of means whereby the temperature of the air while passing from the atmosphere to the interior of the car may be temperedv z', e., cooled or heated, inorder to avoid in- Jury to the fruit being carried in either warm or cold weather.

With the foregoing in mind, the nature of the invention and its novelty, utility and practical advantages will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying `and forming part of this specification, in which:

Figure 1 is a vertical transverse section showing a car body and my improvements; the upper portion of the body being broken away. F ig. 2 is a detail horizontal section of a portion of the car body taken in a plane below the foraminous false floor of the body, and above the air conduits. Fig. 3 is an enlarged longitudinal, vertical section of one of the tanks comprised in my improvements.

Referring by letter to the said drawings: A is a car body which is preferably provided with means for exhausting the same of vitiated or foul air. The said means, however forms no part of my present invention, and therefore l have deemed it unnecessary to illustrate the same. At about the distance illustrated above its ioor a the body A is provided witha foraminous false floor b, as shown in Fig. l.

C C are tanks suspended below the body i' A and arranged longitudinally adjacentto Ithe sides of the body, and D D are pipes contained in and extendin longitudinally` of the said tanks. The ta s C and their systems of pipes are similar in construction, and therefore a detailed description of the I I i tank C shown in Fig. 2 and the system of pipes used in combination with said tanks,

will suffice to impart a definite understands ing of both tanks and pipe systems. p

The pipes D extend longitudinally through the tank at points adjacent to the bottom of i the latter, and each pipe is connected at its outer end to an inductor E arranged exteriorly of the body A and preferably adjacent to a side wall thereof. From its inductor E 'each pipe D extends inwardly through the side wall of the body A and into the space between the floor a and the false floor b and then downward through the floor a and into the tank C adjacent to one end thereof, and then after being carried. longitudinally through the lower portion of the tank to a point adjacent to the opposite end thereof is carried upward through the tank and the floor a of the body into the space between said floor a and the false floor b. Some of the pipes are arranged to discharge at c in the space between the iioors a and Z), while other' pipes are arranged to discharge at d in the upper portions of the corners of the body, and hence it will be manifest that the fresh air taken into the interior of the car will be distributed throughout such interior, and also that the air currents discharged at the points c will meet the air currents discharged at the points d and in that way ,give rise to an agitation of air conducive posite position, this latter in order that when the car is to travel in the direction opposite to the arrow N o. 1, the inductors may be arranged to the best advantage in order to assure the 'plentiful supply of fresh air to the interior of the body A.

The tanks C may be provided with any suitable means for tempering, that is-cooling or heating the air while the 'same is en Toute through the pipes D, and from this it follows that in warm weather the air may be cooled precedent to the supplypof the same to the interior of the body A, and in cold weather the air may be heated before the 'same enters the interior of the body. As shown, each tank C is provided with a removable foraminous bottom g, curved in conformity to and resting close against the series of pipes D, a plurality of removable iool lcn

Y dental to .thel movements of the car` and the passage of the same up and down sharp grades and willl also eectually prevent collection of the ice in one end of the tank. It

will further benoted in this connection that the fora'mi-nous bottom' g will protect the pipes D against ice roughly thrown into the tanks, and this without interfering with the proper cooling of the said pipes. adaptability of the bottoms g and the transverse partitions -L to be removed from the tanks is advantageous inasmuch as -it permits of said bottomy and lpartitions and thev pipes D beingrepaired withv facility when occasion demands.

With a view of draining the pipes D of any water that may be deposited in the same by the, air passing therethrough, thesaid pipes may be equipped at convenient points with drain cocks, but lthese form no part of my invention and hence I have deemed it unnecessary to illustrate the same.

When necessary the tanks C may be supplied with a suitable heating agent instead Vof the cooling agent described.

cost of the same; and the maintenance of dry air in the interior of the car will be appre- -ciated as an important advantage when it is considered thatboth the car and the contents thereof are kept dry, and hence when the car is unloaded it may be immediately' reloaded with any commodity that it is desired to-transport without the necessity of waiting for the car to dry out.

I prefer inpracticeyto detachably connect the transverse partitions h to lugs 72, on the major portions of the tank C, and to depend on the interposition of the ,foraminous bottoms y between the pipes D and the partitions /L to retain the said bottoms in position, hut it is lobvious that the partitions and the ,bottoms'may be detachably secured in the 55 tanjks in any approved manner without involving departure from the scope of my invention as defined in the claim appended.

Having described my invention, what I claim and desire to secure by Letters-Patent,

'The combination of a car body, a tank carried by and extending in the direction of the length of the. body; said tank being circular in cross-section and having a major portion and a door hinged thereto, conduits extending longitudinally through the tank and arranged sidey by side -on the bottom thereof and connecting the interior of the body with the atmosphere, a bottom curved in the direction of the width and removably arranged on said conduits, and transverse partitions detachably fixed in the tankand arranged above and in;l engagement with the said bottom to hold the same down upon the conduits. l

In testimony whereof I have hereunto 'set my hand in presence of two subscribing witnesses.
